HOSE-COUPLING.

To all whom 'it may concern:

Be it known that l. Fnrnmcn G'. SCHArf man, u citizen. of the United States, residing at Wausau. in the county oi Marathon and State of Wisconsin, have invented new and useful Improvements in Hose-Couplers, of which the following is a specification.

This invention relates to hose couplers. and has for an object to provide a device of this character which will include novel forms of connections for receiving the ends of the hose and to further provide simple and novel form of clamping means arranged to draw the ends of the hose toward each other and their connections into such frictional contact with each other as will form a perfect water tight joint.

Other objects and advantages will be apparent as the nature of the invention is better set forth, and it will be understood that changes within the scope of the claim ma)v be resorted to without departing from the spirit of the invention.

In the drawing, forming a portion of this specilcation ano in which like numerals of reference indicate similar arts in the several views z-Fi ure 1 is a ragmentarjv perspective view o my improved coupler showing one of the pipe sections in position to be engaged with tie coupler. Fig. 2 is a detail longxitudinal section taken through a portion of t e coupler. Fig. 3 is a transverse section taken through a portion of the coupler showing the latch member. Fig. l isa perspective view of the coupler showing its enga ement with alining pipe sections.

eferrin now more particularly to the drawing, tiere is shown a hose coupling comprisin a member or sleeve lprovided at one end with a cutaway portion or recess Q, andas shown said member or sleeve is provided With an arcuate or annular flange 3 and with shoulders 4; which are disposed in spaced relation to the tiange. The member or similar hollow element 5 which is provided with a reduced end portion 6 is corruated exteriorly as illustrated at 'T so that a ose or similar flexible connection S can be engaged at one end with the said corrugated re uced portion of the sleeve or element 5. A sleeve or member 9 is used in conjunction with the sleeve 1 and is provided with a pair of, spaced rings or flarges 10 which are ada' ted to straddle the ange 3 at one end of the sleeve 1. As illustrated the inner end of the sleeve or member 9 is provided with an extension 11 which is disposed in a p0rtion of the sleeve 1 for a purpose to be hereinafter more iullv explained. The sleeve or member 9 is corrugated upon its exterior surface and has secured thereto one end of a hose or flexible connection 12. The sleeve or hollow element Zi. upon its inner end is rabbeted intcriorlv as illustrated at 13 and is adapted for overlapping engagement with the extension 11 of the sleeve or member 9. The rahbeted portion 13 of the sleeve or element 5 has seated therein an elastic washer or packing 1l which is adapted t0 be frictionallv engaged with the inner annular face of the extension 11 so as to form, when the coupling is in its operative position a perfeet water tight joint as will be readily understood.

The sleeve or hollow element 5 is rovided with a pair of pivoted arms 15 w lich have their free ends secured to a yoke or operating lever 16 as shown. The arms 15 have pivoted thereto the outer extremities of links 1T, the inner extremities of said links being pivotall)Y en aged with studs or the like 18 which exten horizontallyv from the member or sleeve 1. The arm 19 of the yoke 16 is provided with a hooked extremity .20 which is adapted to receive one end of a spring latch member `21 which is pivotally connected to the arm 22 of the yoke.

In operation, assuming the ends of the hose or flexible connections to be engaged as hereinbefore described with the sleeves 5 and 9, the sleeve or member 9 is lifted bodily and inserted in the cutawaY .portion of the sleeve 1 so that the nanges or rings 10 straddle the flange 3 in a manner that will effectivel)v prevent sliding longitudinal movement of the sleeve or member 9. Assuming the arms l5 to be in their vertical positions, it will be seen that upon movement of the yoke 16 in the direction of the arrow indicated in Fig. l the links 1T will be moved downwardljv at their outer ends so that their points of pivotal engagement with the arms 15 will occupy points below the points of pivotal enga ement of the arms 15 with the sleeve or hol ow element 5. When'the yoke 16 has been moved downwardljT to the ex` tent of its movement the arms 19 and 22 straddle a portion of the hose 8, and by providing the latch member 21 it is obvious that it can be operated so that its free extremity can be engaged with the hooked portion 20 of the arm 19 in order that the yoke 16 can be held in its operative position. in this operation of the yoke; i' will be appreciated that the sleeve or hollow element 5 will be moved longitudinally in the sleeve l and the inner extremity of'said sleeve will be brought into overlapping engagement with the extension l1 of the sleeve 9 and the said extension will be engaged with the elastic washer or packing 14 to the extent that a perfect water tight joint is formed at this point.

I claim zh A coupling of the class described comprising slidably mounted sleeves, a pair of arms ivotally connected to one of the sleeves, links connecting the otherl sleeve with said arms, a lever o eratively connected with the arms for rocking them to move one sleeve 0n the other, a hose carried by one of the sleeves, a hose carrying member adapted for locking engagement with the other sleeve and provided with an extension upon its inner end adapted for engagement with the inner end of the sliding' sleeve, saidlever ,having a pan oi spaced arms which are adapted to straddle a portion of the hose and to extend downwardly beneath the same, one of said arms having a slot formed therein, and a latch member carried by the other arm adapted to underlie the hose and to be secured in the slot to hold the sleeves against movement on each other.

In testimon whereof I aflix my signature in presence o two witnesses.
